Patent number: 8848701Abstract: Different access networks may perform signaling and data delivery (bearer connection) for communication services. A device may determine, in response to a request for a service from a user of the device, whether the device is connected to a non-cellular access network. The device may transmit, when it is determined that the device is connected to the non-cellular access network, one or more control messages, relating to establishment of the service, using the non-cellular access network. The device may transmit, when it is determined that the device is not connected to the non-cellular access network, the one or more control messages, using a cellular access network. The device may establish, with a party with which the service is to connect, a bearer connection for the service over the cellular access network.Type: GrantFiled: June 30, 2011Date of Patent: September 30, 2014Assignee: Verizon Patent and Licensing Inc.Inventors: Steven R. Rados, John F. Macias, David Chiang, Lalit R. Kotecha, Yee Sin Chan, Jay J. Lee, Thomas W. Haynes

Patent number: 8848702Abstract: One embodiment includes, inter alia, methods, apparatus, computer-storage media, mechanisms, and/or means associated with automated transitioning between different communication protocols in a network. In one embodiment, automatic transition routers are automatically discovered along with the knowledge of what non-native protocols need to be transported across a network. Communication pathways are automatically established as needed to transport these non-native protocols. One embodiment is particularly useful in transitioning a network from one protocol to another, such as from Internet Protocol version 4 to version 6.Type: GrantFiled: February 19, 2011Date of Patent: September 30, 2014Assignee: Cisco Technology, Inc.Inventors: Ole Troan, William Mark Townsley, Gunter Van de Velde, Wojciech Dec

Patent number: 8848703Abstract: A table for changing destination has a destination address in a shared memory and an identifier of a router directly connected to a destination core, in association with each other, and is set by a source core. A search unit performs a first search for searching whether the table has an effective entry having the same address as the destination address in the shared memory, and stored in a header of a write request packet received by the source core. A route calculation unit performs a route calculation with a destination that is a router of an identifier of the entry, if the effective entry is found as a result of the first search. A header generator stores the router identifier obtained by the route calculation in a hop router field of the header of the write request packet, and sets a rerouted flag representing a change in destination.Type: GrantFiled: July 26, 2011Date of Patent: September 30, 2014Assignee: Kabushiki Kaisha ToshibaInventor: Toru Sano

Patent number: 8848704Abstract: A method of facilitating network routing using virtualization includes receiving, at a second device via a virtual machine for a network connection that virtualizes network capabilities of the second device, a packet transmitted by a first device, the packet including a header and a payload, the virtual machine being spawned and managed by virtual dispersive routing (VDR) software; loading, by the VDR software, information from the packet into memory of the second device; appending, by the VDR software, to the payload of the packet, information associated with the second device; and transmitting the packet to a third device using the virtualized network capabilities of the virtual machine.Type: GrantFiled: September 23, 2011Date of Patent: September 30, 2014Assignee: Dispersive Networks Inc.Inventor: Robert W. Twitchell

Patent number: 8848706Abstract: A console is provided and includes a switch and a network device. The network device includes a switch port, first network ports, and a controller. The switch is separate from the network device. Each of the first network ports receives a frame of data, and inserts source information into the frame of data. The source information in each frame of data identifies the first network port that received the frame of data. The controller transfers each frame of data, including the source information, to the switch via the switch port. The switch: adds to each frame of data, destination information identifying one or more of the first network ports; and transfers each frame of data, including the source and destination information, to the switch port. The controller transfers each frame of data, received from the switch port, to the first network ports.Type: GrantFiled: August 21, 2012Date of Patent: September 30, 2014Assignee: Marvell International Ltd.Inventors: Donald Pannell, Partho Mishra

Patent number: 8848707Abstract: Prefix length memory tables are used to enable fast IPv4 LPM lookups using a single memory access for a first range of IP prefixes, and using two memory accesses for larger IP prefixes. Each of the prefix length memory tables is used to hold a set of forwarding rules associated with a different prefix length range. IP LPM operations are then performed in parallel in each of the prefix length memory tables of the set, and the forwarding rule matching the longest prefix is returned from each of the memory tables. A priority encoder is used to select between positive results from the multiple prefix length memory tables to enable the forwarding rule with the largest matching prefix to be used to key into the next hop forwarding table. The method utilizes low cost DDR SDRAM rather than TCAM, and also exhibits low overhead.Type: GrantFiled: September 26, 2012Date of Patent: September 30, 2014Assignee: Avaya Inc.Inventor: Hamid Assarpour

Patent number: 8848708Abstract: The present invention relate to a packet processing method, an access device, and a communication system. The method includes: receiving, by an access device, a multicast packet from a network side via a first network port of the access device; identifying, by the access device, a protocol type of the multicast packet; if identifying that the multicast packet is a virtual router redundancy protocol packet, sending the virtual router redundancy protocol packet via a second network port of the access device to the network side according to a snooping port list used for forwarding the virtual router redundancy protocol packet; and if identifying that the multicast packet is a non-virtual router redundancy protocol packet, sending the non-virtual router redundancy protocol packet via a user port of the access device to a user side.Type: GrantFiled: June 18, 2012Date of Patent: September 30, 2014Assignee: Huawei Technologies Co., Ltd.Inventors: Bin Huang, Zhiyong Yan

Patent number: 8848709Abstract: Methods and apparatus for source rooted multicast (SRM) are provided. As defined herein, SRM generally refers to associating outgoing interface lists (OILs) in the forwarding entry with the source address instead of the group address and aggregating the resulting multicast forwarding states. In this manner, the amount of forwarding state may be reduced, especially in deployments where many hosts are all running the same application and using the same group. One example method generally includes—for each of a plurality of multicast forwarding states associated with a multicast group, wherein each multicast forwarding state is referenced by a source address representing a multicast source and is associated with an outgoing interface list—associating the outgoing interface list with the source address; and aggregating the two or more of the multicast forwarding states having the outgoing interface lists associated with the source addresses to form one or more aggregated forwarding states.Type: GrantFiled: June 26, 2012Date of Patent: September 30, 2014Assignee: Cisco Technology, Inc.Inventors: Gregory J. Shepherd, Dino Farinacci, Jeff Byzek

Patent number: 8848710Abstract: The present invention is directed towards a method and system for providing a technique referred to as flash caching to respond to requests for an object, such as a dynamically generated object, from multiple clients. This technique of the present invention uses a dynamically generated object stored in a buffer for transmission to a client, for example in response to a request from the client, to also respond to additional requests for the dynamically generated object from other clients while the object is stored in the buffer. Using this technique, the present invention is able to increase cache hit rates for extremely fast changing dynamically generated objects that may not otherwise be cacheable.Type: GrantFiled: July 25, 2012Date of Patent: September 30, 2014Assignee: Citrix Systems, Inc.Inventors: Prabakar Sundarrajan, Prakash Khemani, Kailash Kailash, Ajay Soni, Rajiv Sinha, Saravana Annamalaisami, Bharat Bhushan K.R., Anil Kumar
